Thin water lenses floating on top of the main groundwater body are important for many natural and agricultural systems, owing to their different properties in terms of chemical composition or density compared to the surrounding groundwater. In settings with upward seeping groundwater, lenses may form that have thicknesses ranging from tens of centimeters to a few meters, making them prone to changing conditions in the short (seasonal) or long term (climate change). Knowing their thickness, shape, movement and mixing zone width may help in managing these lenses.

向上和向下渗流产生的土壤水之间的界面和混合区 - 第一部分：均匀的总密度


漂浮在主要地下水体顶部的薄水透镜体对许多自然和农业系统都很重要，因为它们在化学成分或密度方面的特性与周围的地下水相比不同。在地下水向上渗漏的环境中，可能会形成厚度从几十厘米到几米不等的透镜体，这使得它们容易受到短期（季节性）或长期（气候变化）条件变化的影响。了解它们的厚度、形状、运动和混合区宽度可能有助于管理这些晶状体。
